DESCRIPTION
Dual Input Charger
The bq24165, bq24166 and bq24167 are highly
integrated single cell Li-Ion battery charger and
20V Input Rating, With Over-Voltage
system power path management devices targeted for
Protection (OVP)
space-limited, portable applications with high capacity
6.5V for USB Input
batteries. The single cell charger has dual inputs
10.5V for IN Input
which allow operation from either a USB port or
higher power input supply (i.e., AC adapter or
Integrated FETs for Up to 2.5A Charge Rate
wireless charging input) for a versatile solution. The
Up to 2.5A from IN Input
two inputs are fully isolated from each other and are
Up to 1.5A from USB Input
managed by the bq24165/166/167 with the IN input
having precedence.
Highly Integrated Battery N-Channel MOSFET
Controller for Power Path Management
APPLICATION SCHEMATIC
Safe and Accurate Battery Management
Functions
0.5% Battery Regulation Accuracy
10% Charge Current Accuracy
Adjustable Charge Current, Input Current
Limit, and VINDPM Threshold (for IN input)
Easy JEITA Implementation
Charge Parameter Selector Inputs (CE1,
CE2) for (bq24165)
Voltage-based, NTC Monitoring Input (TS)
Standard Temperature Range (bq24166)
JEITA Compatible (bq24167)
Thermal Regulation Protection for Output
Current Control
Low Battery Leakage Current, BAT Short-
Circuit Protection
Soft-Start Feature to Reduce Inrush Current
Thermal Shutdown and Protection
Available in Small 2.8mm x 2.8mm 49-ball
